I LUID-CIRCULATING PLATE.

Original application filed August 20, 1925, Serial No. 51,374. Patent No. 1,621,742, dated March 22, 1927.

Divided and this application filed June 14, 1926. Serial No. 115,858.

This invention relates to improvements in the steam or fluid-circulating plates which are employed more particularly in hydraulic presses for vulcaniz'ing and similar uses.

This application is a division of my application Serial'No. 51,374, filed August 20th,v

1925, now Patent #1,621,742.

Its object is the provision of a simple and inexpensive'plate of this character whrch effectually provides for the uniform dlstribution of the heating or cooling fluid over its entire area, and which is so constructed that the fluid passages can be readily and thoroughly cleaned out in a minimum period of time.

In the accompanying drawings: Flgure 1 is a top plan View, partly in section, of one of the plates. Figure 2 i an end view thereof, the cover being partly broken away. Figure 3 is a fragmentary transverse section on line 33, Fig. 2.

Similar characters of reference indicate corresponding parts throughout the several views.

In the preferred embodiment of the invention illustrated in the drawings, 10 indicates the plate which is rectangular in plan and made of rolled steel or similar material. Extending horizontally through the body of the plate are a plurality of parallel circulat- 111g channels 11 formed by drilling through the plate from one end thereof to the op posite end. For the purpose of establishing communication between the several channels to provide a circuitous course for the fluid through the same, their outer ends are connected by transverse ports or passages 12 disposed in the alternate spaces between the channels, as shown in Fig. 1. These ports are preferably formed by planing or milling of the plate between each pair of channels 11, the ports in one end of the plate being staggered with respect to those in the op posite end, whereby the fluid is caused to circulate in a sinuous course cover the entire area of the plate.

The open ends and front sides of the channels 11 and ports 12, respectively, are closed or covered by steel plates 13, which extend over the grooved ends of the plate and are securely fastened thereto by bolts l l. .These plates are preferably seated in corresponding recesses 15 and a suitable packing 16 'of asbestos or copper is interposed between each cover and the opposing side wall of the plate.

The outermost channel 11 at one side of the plate has a fluid inlet 17 while the corresponding channel at the opposite side of the plate has a fluid outlet 19.

This improved steam plate is very easy to manufacture, its machining operations are few, and it can be produced at a moderate cost. Furthermore, the construction and arrangement of the channels and ports materially, facilitate the cleaning thereof from time to time, it being only necessary to remove the cover plate 13 for this purpose.

I claim as my invention:

1. A. circulating plate of the character described, having a plurality of fluid-circulating channels extending through the same from one end thereof to the other and ports formed by grooves cut in the opposite ends of the plate transversely of and connecting each pair of channels, a cover plate extending substantially the full width of the circulating plate and closing the-ends of said channels and the open sides of said ports,

and means for detachably holding said cover plate in place. r

2. A circulating plate of the character described, having a plurality of fiuid-circulating channels extending through the same from one end thereof'to the other and having a common inlet anda common outlet,

transverse grooves in the opposite ends of the plate arranged alternately between each pair of channels, and cover plates applied to the grooved ends of the circulating plate for closing'the ends of said channels and the open sides of said grooves, each cover plate extending transversely of the circulating plate over the corresponding ends and sides of the several channels and grooves, respectively.

3. A circulating plate of the character de- 7 scribed, having a plurality of fluid-circulating channels having a common inlet and a common outlet and a recess in two opposing end Walls thereof, the channels opening into said recesses, transverse grooves in the hot toms of said recesses forming connecting ports between said pair of channels,-- the grooves at one side of the plate being staggered with respect to those in the opposite side, coverplates seated in therecesses for closing the ends of said channels and the open sides of said grooves, each cover plate being common to the several channels and grooves. opening inthe corresponding recess, and means for detachably securing 4 said cover plates in place.
